In the early years of the European discovery and exploration of theNew World, the land that became Trumbull County was originally claimed by French explorers as part of the French colony ofCanada (New France). Their settlements had somefur traders who interacted with Native American tribes in this area. After losing theSeven Years' War to Great Britain, France was forced to cede its territories east of the Mississippi River in 1763.Great Britain renamed New France as theProvince of Quebec.
Following the United States' victory in its Revolutionary War, the British were forced to cede this land to the new nation. The federal government convinced Connecticut to give up its claim to the land, but it was known as part of theConnecticut Western Reserve in theNorthwest Territory. Connecticut retained sovereignty over some of the eastern portion of what became Ohio, selling this area in 1795 to theConnecticut Land Company, a speculative private development firm. As first organized, Trumbull County consisted of the entire area of the Connecticut Western Reserve before population increased, and it was divided into smaller counties. The county's main city, Warren, was originally founded as the capitol of the Western Reserve territory.[5]
No Native American settlements have ever formally been identified in Trumbull County; however, artifacts are uncovered often. Early settlers did believe they noted an ancient village site in Kinsman, a more contemporary site in Hartford, and several strange stone constructions were noted in the Black Ash Swamp by early Bristol residents- this area now known as the Grand River Preserve. Many presumably different groups of Natives were still frequenting camps in the vicinity of Newton Falls and somewhere near the Champion-Warren township border when modern Americans first began to settle there. Several of the names of specific Native persons are echoed across most of these early residents' histories- namely Cadashaway, Paqua and Kiogg. A memorial stone piles believed to have been Native in origin was situated on the West Bank of the Mahoning, but was later removed for construction purposes.[6] Before 1600, the area was ambiguously between the territories of the Erie people to the east and the Whittlesey Culture to the west. It is currently unknown precisely where one tribe's territory ended and the other began. After the Beaver Wars, the area was frequented by travelling Lenape, Wyandot, Ottawa, Shawnee and Seneca, who all had settlements nearby for a time and shared the valley's animal, food and medicinal resources. They also regularly panned for salt in the marshes. The Natives collectively used this area as a shared hunting ground, but had to give up ownership of the region for settlement as punishment for participating in the Northwest Indian War.[7] However, early residents say Natives still frequented the area until roughly 1811. Some of the final Native residents were camped along the Grand River in Mespotamia during the war, leading to an upsetting altercation in which the locals found and ransacked their camp and, as a warning to leave, carved an image of a Native man into a tree and shot it. The Natives responded by carving a white man into a tree without a mark on it, but seem to have later felt it was unsafe to stay and left. They could have gone south to Prophetstown, a religious compound run by Tecumseh's brother, and got caught up in theShawnee War andWar of 1812, or they and several other Native communities scattered around northeast Ohio may have condensed into a handful of settlements in the Cuyahoga River, before the majority of them relocated west in 1813 to either live with the main Ottawa or Wyandot tribe. Only a handful of Native individuals were left throughout all of Northeast Ohio and historically recorded following this.[8]
